Sensors may be seniors' at-home safety net

It could mean no more having to check up on Mom or Dad every morning: Motion sensors on the wall and a monitor under the mattress one day might automatically alert you to early signs of trouble well before an elderly loved one gets sick or suffers a fall.

Research is growing with high-tech gadgets that promise new safety nets for seniors determined to live on their own for as long as possible.

"It's insurance in case something should happen," is how Bob Harrison, 85, describes the unobtrusive monitors being tested in his apartment at the TigerPlace retirement community in Columbia, Mo.

Living at home -- specialists call it aging in place -- is what most people want for their later years.

Americans 40 and older are just as worried about losing their independence as they are about losing their memory, according to a recent survey by the Associated Press-NORC Center for Public Affairs Research.

Common-sense interventions like grab bars in bathrooms and taping down rugs to prevent tripping can make homes safer as seniors deal with chronic illnesses. Technology is the next frontier, and a far cry from those emergency-call buttons seniors sometimes wear to summon help.

Already some companies are offering monitoring packages that place motion sensors on the front door, a favorite chair, even the refrigerator, and then send an alert to a family member if there's too little activity over a certain period of time.

Other gadgets can make pill bottles buzz when it's time for a dose and text a caregiver if it's not taken, or promise to switch off a stove burner that's left on too long.

Researchers at the University of Missouri aim to go further: Their experiments show that certain automatic monitoring can spot changes -- such as restlessness in bed or a drop in daytime activity -- that occur 10 days to two weeks before a fall or a trip to the doctor or hospital.
